Welcome to GPNi UK, your go-to platform for globally recognised sports nutrition courses. Today, we delve into the intricate world of protein absorption, seeking to answer a common question: How much protein can your body truly absorb? As we explore this topic, we'll unravel the science behind protein intake, distribution, and its various metabolic rates. 
The myth of 20-30 grams per meal: 
You may have come across the recommendation that your body needs around 20-30 grams of protein per meal for optimal muscle protein synthesis. Contrary to a common misconception, this doesn't imply your body can only absorb or utilise that much. Rather, it suggests that, according to current research, this distribution pattern seems effective for those focusing on muscle building and recovery. 
Optimising muscle protein synthesis: 
Studies indicate that consuming about 30 grams, or around 2-3 grams of leucine, is sufficient to stimulate muscle protein synthesis. However, exceeding 40 grams does not necessarily lead to further stimulation. It's important to note that this doesn't mean your body can't absorb more; rather, it suggests a threshold for optimal muscle protein synthesis. 
Beyond 30 grams: Your body's resilience: 
Your body is a complex and adaptive system. While it's true that the recommended amount for muscle protein synthesis may be around 30 grams per meal, your body can absorb more, theoretically, an unlimited amount. Excess protein serves various purposes, from being broken down into amino acids for later use to being utilised by different organs and even excreted in the stool. 
Excess protein and metabolic fate: 
Contrary to the misconception that excess protein gets stored as fat, studies show that the metabolic fate of excess protein is diverse. It can be broken down into amino acids, stored in an amino acid pool, used for lean tissue (especially with resistance training), or even increase metabolic rate. In a calorie surplus, excess protein may contribute to fat storage, but it can also lead to increased lean tissue, metabolic rate, and fat loss under specific conditions. 
10 Best sources of protein 
Protein is an essential macronutrient crucial for muscle repair, immune function, and overall well-being. These top 10 sources of protein provide a diverse range of options for those seeking to meet their daily protein requirements. Starting with chicken breast, a lean favourite, it packs approximately 31 grams of protein per 100 grams, making it a staple for many fitness enthusiasts. Eggs, a nutritional powerhouse, offer around 13 grams per two large eggs, providing not only protein but also essential amino acids. For plant-based options, lentils shine with about 9 grams per half-cup when cooked, making them an excellent choice for vegetarians. Greek yogurt, known for its creamy texture, boasts roughly 10 grams per 100 grams, making it a versatile and tasty protein source. Other notable mentions include salmon (25 grams per 100 grams), cottage cheese (11 grams per half-cup), chickpeas (7 grams per half-cup), tofu (8 grams per 100 grams), almonds (21 grams per 100 grams), and quinoa (8 grams per cup). Incorporating these protein-rich foods into your diet ensures a well-rounded approach to meeting your daily protein needs. 
In conclusion, don't fret if you consume more than 30 grams of protein in one meal. Your body is a remarkable and adaptable system, efficiently utilising nutrients based on its needs. Whether you're aiming for muscle building, energy balance, or fat loss, understanding the diverse metabolic fate of protein empowers you to make informed dietary choices.
